Options 7 Options 7.1 Magnetic Tape The magnetic tape consists of 3 components (see picture 5) • a magnetized flexible rubber tape (pos. 3), which is connected factory made with a • steel band (pos. 5) and a • covering band (pos. 1) , which is intended for the protection of the rubber tape. •...
Options 7.1.2 Processing Note for Sticking The provided sticky tapes stick well on clean, dry and plain surfaces. The worse the pollution at the place of instalment, the better the sticky tapes should be. A surface roughness of R <= 3.2 (R <= 25 / N8) is recommendable.
Operation / Interference 8 Operation 8.1 Offset After the installation of the magnetic tape and the measuring system (sensor head), a value is transmit by the interface. Because this value does not conform to the machine zero point, an offset should to be deposited at the controller side.
Interference / Maintenance Electrical Interference Suppression The shield of signal output cable should only be connected one-way to the following electrical device. Signal wires should be installed separately from load power lines and with a safe distance of at least 0.5 m to capacitive and inductive interferences such as contactors, relays, motors, switching power supplies, timed controllers.
